From Grid5000
Jump to: navigation, search

(F)ind yo(U)r (N)odes on g5(K) is a tool that help you to plan your experiments on Grid'5000. It is a Python script based on Execo that:

  • give you the number of nodes available at a date and for walltime
  • find the slots for a combination of resources and a walltime
  • find the slot with the maximum number of nodes for a period and a walltime.

Some basic examples can be found here.

Running the tool

Inside Grid'5000

Terminal.png frontend:
$ funk -h

See below for options descriptions.

Outside Grid'5000

You need to install execo and configure it for Grid'5000.

You also need python-httplib2 to make use of the request on the Grid'5000 API. If you have no admin rights, install it with :

 easy_install --user httplib2

or

 pip install --user httplib2

Once it is done, you can clone the repository with:

 git clone https://github.com/lpouillo/Funk.git

and run the script.

Usage

I want to find how many nodes are currently available on sites lyon,nancy,rennes for a walltime of 3 hours

Terminal.png frontend:
funk -m date -r lyon,nancy,rennes -w 3:00:00

I have a deadline in one week and I absolutely need to run a large scale experiment on the whole platform (avoiding periods under usage policy restrictions)

Terminal.png frontend:
funk -m max -r grid5000 -w 4:00:00 -e "2014-02-17 16:00:00" -c

I need specific resources combination for my experiments and I want to know when a slot will be available, with deploy job type, and reserve it automatically (-y option) :

Terminal.png frontend:
funk -m free -r taurus:2,nancy:100 -w 10:00:00 -o "-t deploy" -y

Please be aware of the Grid'5000 Usage Policy or use -c to avoid usage policy periods. A walltime for a night reservation is 11:58:00 or is for a weekend 62:58:00.
